Use of Transmission Dyes for Protecting Human Skin From Browning and Ageing

ABSTRACT

Disclosed is the use of an aqueous dispersion comprising (a) a micronized sparingly soluble organic compound which has a UV-Vis spectrum with a maximum from 380 to 420 nm; and (b) an anionic dispersing agent for protecting the human skin from browning and skin aging.

The present invention relates to the use of specific transmission dyes for protecting human hair and skin against UV radiation and skin aging and preventing tanning and cosmetic or dermatological compositions comprising these dyes.

It is known that certain photostable organic UV filters, for example bis-ethylhexyloxyphenol methoxyphenyl triazine, methylene bis-benzotriazolyl tetramethylbutylphenol disodium phenyl dibenzimidazole tetrasulfonate or terephthalylidene dicamphor sulfonic acid or butyl methoxy dibenzoyl methane which is photo-stabilized with octocrylene exhibit pronounced UV filtering properties in the UV-A range up to 380 nm. In the range from 380 nm to 420 nm no satisfactory UV protection can be achieved.

However, it is known that in the region>380 nm the sun light significantly contributes to skin aging and enhanced skin cancer risk.

Surprisingly it was found that specific UV absorbers which have absorption maxima above 380 nm show no significant color when applied to the skin.

Therefore the present invention relates to the use of an aqueous dispersion comprising

(a) a micronized sparingly soluble organic compound which has a UV-Vis spectrum with a maximum from 380 to 420 nm; and (b) an anionic dispersing agent for protecting the human skin from browning and skin aging.

Preferably the organic micronized UV absorbers are selected from benzophenone derivatives.

The cosmetic or pharmaceutical preparations can be prepared by physically mixing the UV absorber(s) with the adjuvant using customary methods, for example by simply stirring together the individual components, especially by making use of the dissolution properties of already known cosmetic UV absorbers, like octyl methoxy cinnamate, salicylic acid isooctyl ester, etc. The UV absorber can be used, for example, without further treatment, or in the micronised state, or in the form of a powder.

Cosmetic or pharmaceutical preparations contain from 0.05-40% by weight, based on the total weight of the composition, of one UV absorber or UV absorber mixtures.

Of special interest are mixing ratios of from 20:80 to 80:20, preferably from 40:60 to 60:40 and most preferably approximately 50:50. Such mixtures can be used, inter alia, to improve the solubility or to increase UV absorption.

The compounds of formula (1) may also be used as an anti-wrinkle perception modifier.

This is a further object of the present invention.

The cosmetic or pharmaceutical preparations may be, for example, creams, gels, lotions, alcoholic and aqueous/alcoholic solutions, emulsions, wax/fat compositions, stick preparations, powders or ointments. In addition to the above mentioned UV filters, the cosmetic or pharmaceutical preparations may contain further adjuvants as described below.

As water- and oil-containing emulsions (e.g. W/O, O/W, O/W/O and W/O/W emulsions or microemulsions) the preparations contain, for example, from 0.1 to 30% by weight, preferably from 0.1 to 15% by weight and especially from 0.5 to 10% by weight, based on the total weight of the composition, of one or more UV absorbers, from 1 to 60% by weight, especially from 5 to 50% by weight and preferably from 10 to 35% by weight, based on the total weight of the composition, of at least one oil component, from 0 to 30% by weight, especially from 1 to 30% by weight und preferably from 4 to 20% by weight, based on the total weight of the composition, of at least one emulsifier, from 10 to 90% by weight, especially from 30 to 90% by weight, based on the total weight of the composition, of water, and from 0 to 88.9% by weight, especially from 1 to 50% by weight, of further cosmetically acceptable adjuvants.

-   -   in the form of liquid preparations as a W/O, O/W, O/W/O, W/O/W         or PIT emulsion and all kinds of microemulsions,     -   in the form of a gel,     -   in the form of an oil, a cream, milk or lotion,     -   in the form of a powder, a lacquer, a tablet or make-up,     -   in the form of a stick,     -   in the form of a spray (spray with propellent gas or pump-action         spray) or an aerosol,     -   in the form of a foam, or     -   in the form of a paste.

Of special importance as cosmetic preparations for the skin are light-protective preparations, such as sun milks, lotions, creams, oils, sunblocks or tropicals, pretanning preparations or after-sun preparations, also skin-tanning preparations, for example self-tanning creams. Of particular interest are sun protection creams, sun protection lotions, sun protection milk and sun protection preparations in the form of a spray.

Of special importance as cosmetic preparations for the hair are the above-mentioned preparations for hair treatment, especially hair-washing preparations in the form of shampoos, hair conditioners, hair-care preparations, e.g. pretreatment preparations, hair tonics, styling creams, styling gels, pomades, hair rinses, treatment packs, intensive hair treatments, hair-straightening preparations, liquid hair-setting preparations, hair foams and hairsprays. Of special interest are hair-washing preparations in the form of shampoos.

Other typical ingredients in such formulations are preservatives, bactericides and bacteriostatic agents, perfumes, dyes, pigments, thickening agents, moisturizing agents, humectants, fats, oils, waxes or other typical ingredients of cosmetic and personal care formulations such as alcohols, poly-alcohols, polymers, electrolytes, organic solvents, silicon derivatives, emollients, emulsifiers or emulsifying surfactants, surfactants, dispersing agents, antioxidants, anti-irritants and anti-inflammatory agents etc.

The cosmetic preparation according to the invention is distinguished by excellent protection of human skin against the damaging effect of sunlight.

EXAMPLES Preparation of UV Absorbers Example 1 Preparation of the Compound of Formula

59.0 g 3 diethylamino-dibenzo-oxepin of formula

(prepared according to Example 1 of WO 204/052837) are dissolved in 250 ml acetic acid ethyl ester at room temperature.

8.6 g piperazine are added to this solution with stirring whereas the temperature rises to 40° C.

The product precipitates during adding of the reaction mass.

Then the suspension is stirred for about 3 h under reflux, filtered off and the residue is recrystallized from 2-methoxy-ethanol.

After drying of the citric yellow crystals 67 g of the end product are obtained.

Fp=253-256° C.

The compound of formula (101) can be obtained in different forms. The single crystal forms are characterized by their x-ray diffractograms.
